"Tiny Motors Deliver Ulcer Medication in Mouse Stomachs"
Researchers have built drug-delivery capsules that neutralize stomach acid and use the resulting hydrogen peroxide bubbles to propel themselves and deliver an antibiotic. When tested in mice, the micromotors proved slightly more effective than the same dose of antibiotic delivered orally along with an acidity-lowering proton pump inhibitor, researchers report yesterday (August 16) in Nature Communications.
"Tiny Robots Help Cure Stomach Infections In Mice"
In the not-so-distant future, drug treatments could be delivered straight to the problem area with the help of some very tiny robots. Researchers at the University of California, San Diego successfully treated bacterial gastric infections in mice using micromotors. The use of nanotechnology in medicine is nothing new but this is the first time chemical treatments have been administered in vivo with this kind of technology.
"Researchers Used Tiny Autonomous Vehicles to Deliver Medicine to the Stomach of Mice"
Researchers used autonomous vehicles known as micromotors to cure bacterial infections in the stomachs of mice. Micromotors are only the width of a single human hair, which allows them to negotiate the labyrinthine confines of the human body, and administer precise treatment. In this study, micromotors were used to provide mice with a dose of antibiotics every day for five days. This regimen was found to be more effective than the standard method of administering the medicine.

"Micromotors neutralize stomach acid, deliver antibiotic"
Micromotors thinner than a human hair delivered an antibiotic in the stomachs of mice while neutralizing excess acid, in a study by University of California San Diego scientists. The micromotor-delivered antibiotic reduced populations of H.pylori bacteria, which can cause stomach ulcers. The proof of principle could lead to a safer acid-neutralizing alternative for drug-taking patients than treating them with proton pump inhibitors, which have been linked to various undesirable side effects.

"Tiny robots crawl through mouse's stomach to heal ulcers"
Tiny robotic drug deliveries could soon be treating diseases inside your body. For the first time, micromotors -- autonomous vehicles the width of a human hair -- have cured bacterial infections in the stomachs of mice, using bubbles to power the transport of antibiotics. In mice with bacterial stomach infections, the team used the micromotors to administer a dose of antibiotics daily for five days. At the end of the treatment, they found their approach was more effective than regular doses of medicine.
"Scientists Create A New Way To Deliver Medicine Through Your Stomach"
The acids in our stomachs are great for helping to break down food to digest them, but when it comes to medication, there are some instances where consuming medicine orally might not be the most effective way around it. A team of researchers at UC San Diego might have come up with an interesting method of delivering medicine through your stomach and ensuring that it does not get destroyed by your stomach acids, and that is through the use of micromotors that will change your stomach's pH levels so that the medicine can be delivered safely.
"Robots the size of a human hair cure sick mice -- with bubbles"
Scientists are breaking out the bubbles to celebrate a new breakthrough -- and we're not talking about champagne. Tiny robots the size of a human hair, known as micromotors, have been used to cure bacterial infections in mice using bubbles. A team from the University of California, San Diego used the micromotors to administer a daily dose of antibiotics in the stomachs of mice and found improved results compared with more conventional methods.
"'Micromotors' alter your gut's chemistry to safely deliver medicine"
There's a reason diabetics can't take their insulin orally (for the time being): stomach acid is super effective at dissolving it and similar large proteins, like antibiotics. But rather than force patients to pound pints of Maalox or chew a tub of Tums before taking their medicine, a team of researchers at UC San Diego have developed a novel method of getting your medication past the acid by using nearly microscopic drug delivery vehicles which increase the pH as they swim through your stomach.

"First: Titanium micromotors zip around stomach, fight bacteria"
In what they are calling a world first, nanoengineers at the University of California San Diego (UCSD) have delivered tiny drug-bearing motors into the stomachs of mice where the devices moved around via bubble propulsion. The locomotion method not only allowed the mini molecular machines to navigate, but it also changed the pH of the stomach to allow the successful dispatch of bug-clobbering antibiotics.
"Acid-Powered Micromotors Treat Bacterial Stomach Infection in Mice"
Scientists have for the first time used tiny self-propelling, drug-loaded micromotors to treat a bacterial gastric infection in experimental mice, without the use of acid-blocking proton pump inhibitors. Developed by researchers at the University of California San Diego, the biodegradeable micromotors are less than half the width of a human hair in size and constructed around a magnesium core that reacts with protons in stomach acid to propel the vehicles to the stomach wall, where they attach and release their antibiotic cargo.

"Tiny robots could soon heal stomach ulcers"
Tiny robots could soon be ferrying medicine around the human body, after scientists successfully used the minuscule gadgets to cure sick mice, according to a new report. Researchers at the University of California San Diego used the hair-width bots called "micromotors" to deliver doses of antibiotics to rodents with bacterial stomach infections -- and found they were more successful than just taking the drugs robot-free.

"Ulcer-fighting Robots Swim Through Stomachs to Deliver a Cure"
Tiny robots powered by bubbles have successfully treated an infection in mice. The achievement is another step forward in a field that has long shown promise, and is only now beginning to deliver. The therapeutic robots in this case were tiny spheres of magnesium and titanium coated with an antibacterial agent and about the width of a human hair. They were released into the stomach, where they swam around and delivered a drug to the target before dissolving.
"Nanoengineers Made Antibiotic-Carrying Micromotors to Treat Infections"
Antibiotics are meant to kill bacteria, but sometimes the drugs are sensitive to stomach acid, becoming ineffective on their way to fighting off nasty infections in the gut. Now nanoengineers at the University of California San Diego have figured out how to transport antibiotics directly to the site of an infection, while protecting them from acidity: by sending the medication into the body with "micromotors," little vehicles made of magnesium, titanium dioxide, and a polymer called chitosan, which is made from crustacean shells.

"UC San Diego scientists are building tiny nanobots to swim through your stomach"
The idea of treating disease or carrying out surgery using swarms of tiny robots injected into the human body may sound like science fiction, but it is one that is proving increasingly popular. In a new research project, nanoengineers at the University of California, San Diego have demonstrated the use of tiny "micromotor" nanobots, capable of treating a bacterial infection in the stomach. The lab's tiny vehicles, each one around half the width of a human hair, are able to swim rapidly through the stomach, neutralizing gastric acid and releasing a cargo of drugs at the desired pH level.
"Follow the Bitcoin to find victims of human trafficking"
A team of university researchers has devised the first automated techniques to identify ads potentially tied to human trafficking rings and link them to public information from Bitcoin - the primary payment method for online sex ads. This is the first step toward developing a suite of freely available tools to help police and nonprofit institutions identify victims of sexual exploitation, explained the computer scientists from the New York University Tandon School of Engineering; University of California, Berkeley; and University of California, San Diego.
"3D Printed Models Help Surgeons Work on Kids' Slipped Femurs"
Individual patients undergoing hip surgeries have unique anatomies that demand personalized attention by the surgical team. In children, the level of detail is greater and it's even more crucial to achieve optimal results since the patients will want to run, jump, and swim for many years to come. Teens and pre-teens, and particularly boys, can suffer from slipped capital femoral epiphysis, a condition in which the head of the femur becomes weak and gets squeezed too much, causing a misalignment of how the femur connects with the pelvis.
"New Study Results Show That 3D Printed Surgical Models Can Equal Major Cost and Time Savings"
Having personal experience with the typically agonizing time spent in a waiting room while a loved one undergoes surgery, I am a big fan of anything that safely reduces the amount of time patients have to spend on an operating table, including 3D printed surgical models for training and planning purposes. Medical models, specifically patient-specific ones, allow surgeons to get their eyes, and their hands, on the organ or body part they?ll be operating on ahead of time, which lets them plan out exactly what they need to do during the surgery.

"Transparent 'Window Into the Brain' Lets Sound Waves Through the Skull"
A transparent skull implant is designed to make ultrasound brain surgery easier. The words "hole in the head," as in "[insert organization] needs another reorganization like a hole in the head" is a colorful way of describing something that there is absolutely no requirement for. But sometimes a hole in the head is necessary -- and researchers from the U.S. and Mexico want to help deliver it. With that in mind, they invented a skull implant that serves as a literal window into the brain -- with the goal of making ultrasound brain surgery easier.
